How does the 'Who's up for...' feature work?

"Who's up for..." allows members to initiate fun and creative ideas for a date with members of the opposite sex. Members will see your idea and can click on the'Reply' button starting a private chat. When you press the 'Post' button beneath "Who's up for...", your message will appear for other members. The message will be automatically removed when you uncheck the 'Post' box.
